Has anyone ever had a hemoglobin test done top check for Celiac Disease? Oh and does it hurt? And since I've been gluten free for a while will that affect the test results? thanks!

To my knowledge, and it has been a very long time since my medical training so I may be wrong but this is simply a blood test. I believe it checks the iron levels in your blood. It could be helpful if celiac is causing anemia. It is not a part of the celiac panel used to look specifically for celiac. Being gluten-free will not effect the results of the test.

hi ! no, this test is not for celiac. it is for anemia. you can read more about it here: Open Original Shared Link it doesn't hurt, just a quick, simple blood test. also, if you have been gluten-free for a period of time, it will affect your celiac tests--depending on how long you've been gluten-free, they may make them return negative.

Hemoglobin checks the iron level in your blood. It is a simple blood test and you should have results in a couple days. Going gluten free will have no affect on the results. The test is to check for anemia.

Going gluten-free might actually effect your results if you've been gluten-free for a while (as in quite a few months) and you do have celiac disease, as you might have started absorbing iron better by now and hence not be so anaemic. however, if your dr thinks it's an issue, it is worth getting tested. bad aneamia often does go with celiac disease but isn't diagnostic of it.

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley, which contains gluten, and the standard brewing process does not remove the gluten protein to a level safe for coeliacs (below 20ppm). For someone like you who experiences dermatitis herpetiformis, the reaction is particularly significant. DH is triggered by gluten ingestion, even without immediate gastrointestinal symptoms. So, while you may not feel an instant stomach upset, drinking a gluten-containing beer like Guinness could very well provoke a flare-up of your skin condition days later. It would be a gamble with a potentially uncomfortable and long-lasting consequence. Fortunately, there are excellent, certified gluten-free stouts available now that can provide a safe and satisfying alternative without the risk.

      Interestingly, this thought occurred to me last night. I did find that there are studies investigating whether vitamin D deficiency can actually trigger celiac disease.  Source: National Institutes of Health https://pmc.ncbi.nlm.nih.gov/articles/PMC7231074/

      Before being diagnosed coeliac I used to love Guinness. Being made from barley it should be something a coeliac shouldn’t drink. But taking to another coeliac and they can drink it with no ill effects and have heard of others who can drink it too.  is this everyone’s experience?  Can I drink it?  I get dermatitis herpetiformis and don’t get instant reactions to gluten so can’t try it to see for myself.

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
